Overview
The ColdFusion Upgrade Pre-Flight Checklist (PDF) is a practical, field-tested guide designed to help CFML teams assess, plan, and execute upgrades with confidence. Whether you are moving from Adobe ColdFusion 11/2016/2018 to 2021/2023, migrating from ACF to Lucee, or modernizing an on-prem stack into containers, this Checklist consolidates the critical pre-flight checks you should complete before touching production. It reduces risk, clarifies responsibilities, and streamlines repeatable steps for future upgrades.
What makes this resource valuable is its focus on real-world upgrade blockers—JDK/JVM mismatches, connector issues, datasource changes, Security configurations, and Performance regressions. The PDF doubles as a project artifact you can share across development, DevOps, QA, and Security teams, ensuring everyone follows the same, auditable process.

- Complete the “Environment Inventory” pages:
- Current versions (CFML engine, JDK, connectors, DBs)
- Target versions and desired changes
- Use the “Upgrade plan” template to set timelines, freeze windows, and communication plans.
- Execute checks section-by-section:
- Mark each item as Complete, N/A, or Blocked
- Record evidence and links to commits or config diffs
- Run the “Test Matrix”:
- Unit tests (TestBox), integration tests, load tests (JMeter/Gatling)
- Capture baseline and Post-upgrade metrics
- Finalize “Rollback Playbook”:
- Snapshot backups, database backup/restore procedure, config export
- Validate restore steps in a test environment
- Hold a go/no-go review using the “Sign-Off” page with stakeholders.
Collaborating with Teams

Best practices for a Smooth ColdFusion Upgrade
Preparation
- Inventory everything: CFML engine version, installed packages, Scheduled tasks, datasources, mail servers, caching providers.
- Standardize on a supported JDK version; match to engine requirements.
- Export Configuration: CFConfig exports, ColdFusion Admin settings, web server configs.
- Build a compatibility test matrix:
- Freeze feature development or branch off for upgrade work to avoid code churn.
Execution
- Spin up a parallel environment (blue/green or ephemeral test stack via Docker/CommandBox).
- Reconfigure connectors:
- IIS: BonCode or ACF/IIS connector; confirm handler mappings, application pools.
- Apache: mod_jk or mod_proxy_ajp; confirm worker configs and AJP security.
- Update datasources:
- JDBC drivers matched to DB versions; test connection pools and transaction isolation levels.
- Apply security lockdown guidance:
- Harden admin access, passwords, and IP restrictions.
- Rotate secrets and use environment variables or external vaults.
- Tune JVM:
- Set heap sizes (-Xms/-Xmx) and GC (e.g., G1GC for JDK 11/17).
- Capture GC logs; validate no long pauses or Memory leaks.
- Instrument monitoring:
- FusionReactor/SeeFusion and/or OpenTelemetry exporters for baseline comparisons.
Post-Upgrade Validation
- Run full regression and load tests; compare against pre-upgrade baselines.
- Review logs for new warnings/errors (stack traces, deprecated APIs).
- Validate Scheduled tasks, mail dispatch, file I/O paths, and PDF/Doc features.
- Confirm backups and rollback path still function as expected.
- Document Lessons learned; update your internal runbook for the next upgrade.

How to Adapt the Checklist for Your Stack
ACF to Lucee Migration
- Map proprietary features (e.g., PDFg, cfdocument differences).
- Replace admin settings with CFConfig portable configs.
- Audit tag/function differences and case sensitivity nuances.
Containerized Deployments
- Use CommandBox for lightweight server orchestration.
- Keep CFConfig/ENV vars as code; bake images with known-good versions.
- Implement rolling updates with health checks in Kubernetes.
Highly Regulated Environments
- Embed change-ticket IDs and approvals in the Sign-Off page.
- Capture CVE remediation and patch notes in the Security section.
- Require dual-control signoffs for rollback playbooks.
Key Takeaways
- Use the checklist to create a repeatable, low-risk upgrade process across environments.
- Validate JDK/JVM, connectors, datasources, and security lockdown before you cut over.
- Treat the PDF as a collaborative artifact—assign owners, track evidence, and link to tickets.
- Baseline performance and monitor with APM to catch regressions early.
- Always prepare a tested rollback plan and verify backups before deployment.
FAQ
How is this checklist different from vendor documentation?
It consolidates cross-cutting tasks (JDK, connectors, DB, security, testing, rollback) into one actionable flow, with templates and practical steps tailored to mixed environments—something vendor docs rarely provide in a single place.
Does the checklist cover both Adobe ColdFusion and Lucee?
Yes. It’s engine-agnostic and highlights where behavior differs, with notes for ACF 2018/2021/2023 and Lucee 5.x+ compatibility checks.
Can I use this for containerized upgrades?
Absolutely. The templates include examples for CommandBox, Docker image strategy, and Kubernetes rolling or blue/green deployments, plus CFConfig-based Configuration as code.
Will this help with zero-downtime upgrades?
Yes. The deployment section outlines blue/green and rolling strategies, health checks, session handling, and cutover validation to achieve minimal or Zero downtime.
What prerequisites should I have before starting the checklist?
Ensure you know your current versions, have access to configurations (Admin, CFConfig exports), can run test suites (unit/integration/load), and have permissions to modify web servers, datasources, and monitoring tools.
